We may be small but we pack a punch in the flavour and nutrition stakes. You see we have the ability to bring out the flavour of other foods, as well as tasting great ourselves. And we’re packed full of vitamin C - that’s how English sailors got the nickname Limeys, because lime juice was given to them when they were at sea to stop them getting a disease called scurvy, which is caused by a lack of vitamin C. So you see, we have a lot to offer. Let me tell you more.
We’re thin-skinned, glossy-green to yellow in colour, with beautiful green flesh. Round to almost egg-shaped, about 5cm long, we have a small point at one end. Inside, our flesh is divided into segments by very thin membranes; each segment containing hundreds of little translucent bags which hold our juice. We have an attractive scent and tangy acid flavour.
Our peak season is from January to April but we’re generally available all year round.
Did you know?
• As I mentioned before for hundreds of years, sailors and explorers have eaten us to prevent scurvy on long sea voyages
• We actually increase in weight after we’ve been picked
• We turn yellow as we ripen and become juicier and sweeter
• We’re more fragrant and more acidic than lemons.
Although we’re not sold by variety there are two major types to be found in Australia.
||West Indian lime, also called Mexican or Key lime
We’re a round to oval lime, yellow in colour, with a tart flavour and distinct smell. We prefer to grow in a hotter climate than other limes.
We’re oval in shape, green in colour with a subtle flavour and smell. We’re seedless and much larger than the West Indian variety and grow better in colder climate. We’re Australia’s favourite lime and are even exported overseas.
Why Limes Are Good To Eat
• Like all citrus fruit we’re rich in vitamin C. 100ml of our juice has 47mg of vitamin C - more than the 40mg recommended intake for a day.
• We’re also a good source of pectin, a type of soluble fibre. In some studies, soluble dietary fibre has been shown to help reduce blood cholesterol.
• We’re very low in sugars which is why we taste sour. 100g has 120kJ and only 1g of natural sugar (for comparison 100g orange has 8g sugar).
How They are Grown and Harvested
We grow in tropical and sub-tropical climates and so are used to replace lemons in areas such as parts of Asia, Central America and in northern parts of Australia, where lemons won’t grow.
We’re a citrus fruit related to the orange, lemon, mandarin and grapefruit. Our parent tree is smaller (2.5-4.5 metres) and more attractive than the lemon but has all the citrus characteristics - evergreen, rounded shape with dense, glossy pale green to dark green leaves and white fragrant flowers. We form over a period of time and are picked as we mature. We are harvested by hand so that damage is minimised.
Select those of us that are glossy green and feel heavy for our size.
How to Keep Limes
We’re sold ripe and ready to use. Store us in a fruit bowl. Use within 7 days. Refrigerate for extended storage.
Prime Growing Areas
History of Limes
We, the Persian or Tahitian lime, have an obscure origin possibly coming from the Orient by way of Persia and the Mediterranean to Australia, South America and California in the US. We have been grown in Australia since early 1824.
Our cousin, the West Indian lime, sometimes called the true lime, originated in the Malaysian region of south-west Asia. It has been cultivated in all areas where the climate is suitabl.
As I mentioned earlier, scurvy, caused by the lack of vitamin C, was the curse of long sea voyagers because of its debilitating symptoms. The absence of fresh fruit and vegetables in the diet caused the problem and Captain Cook is said to have been the first to overcome scurvy at sea by always having limes available.
Lime trees were obtained from Rio de Janeiro, Brazil, by the First Fleet on their way to Australia. It’s assumed they were planted with the other citrus trees when the colonists arrived at Sydney Cove in 1788.
Fun Ways to Eat and Cook Limes
We’re similar to lemons and can often be substituted in recipes for each other. Our skin is very thin but the zest is good for flavouring and should be grated before cutting to obtain juice or flesh.
We’re very refreshing in drinks, sorbets, mixed with butter, pies, custards and with vegetables and fish. Our juice brushed over some fruits will stop them browning.
Try some of these tasty lime recipes.
Put zest and juice of 1 lime into measuring jug. Add 1 packet of lime jelly and make up to 150ml with boiling water. Allow to cool but not set.

Lime Meringue Pie
